[0003]

[Problems to be solved by the invention] Support pile 80 shown in FIG.
Since the whole is integrally molded in concrete, the mold for manufacturing is complicated and the manufacturing cost is high,
Due to the large weight of the product, there were problems with transportation costs and construction costs. Further, since each support pile is individually erected, its strength is weak, and it is easily affected by ground subsidence, and the cable trough may meander or collapse in severe cases. Assembling a steel frame to make a stand on site has the advantage that it can be constructed according to the topography of the site and can be made with sufficient strength, but cutting and drilling of the steel frame, welding and rust prevention treatment are performed on site. Since it had to be done, it required a very complicated work, required a sufficient construction period, and was expensive. The present invention has been made to solve the above-mentioned conventional problems, and is made to provide a trough stand that is easy to work on site and has excellent strength.
